Abstract
The data on the dynamics of e-waste generation in different countries are presented and modern methods of handling this type of waste are analyzed. The characteristics of the component composition of electronic waste are given. The problem of neutralization and disposal of mobile phone screens has been studied. An analysis of possible methods for extracting metals from electronic waste has been carried out, which has shown the promise of a biotechnological method based on the ability of the biomass of microscopic algae to selectively, under certain conditions, sorbs metals. Based on the analysis of the research results of domestic and foreign scientists presented in the literature the process of extracting indium from the screens of mobile phones using microscopic algae was simulated under laboratory conditions. When justifying the choice of indium as an extractable metal, two criteria were used: limited distribution in the earth's crust and the difficulty of obtaining from natural ores, as well as demand in various industries. In experimental studies, the parameters of the effective extraction of indium by the biosorption method have been determined.
